Photovoltaics is the conversion of sunlight into electrical energy at the atomic level. Photoelectric materials absorb photons of light and release electrons, resulting in electricity.
Here's how it works:
Solar cells are comprised of semiconductor materials, such as silicon. A thin semiconductor sheet is treated to form an electric field with both a positive and a negative side, forming an electrical circuit. When enough sunlight absorbs in the solar cell, electrons are dislodged from the atoms in the semiconductor material and are collected as electrical current.
Solar cells generate Direct Current (DC) electricity, which can be used to charge batteries. From there, batteries can charge devices that use DC electricity. However, most electricity is utilized through Alternating Current (AC). Devices called Inverters convert the DC electricity to AC electricity.
Photovoltaic or Solar cells convert sunlight into renewable energy. PV cells are connected to form a Solar Panel. Multiple panels can be connected to form a PV array. The number of PV modules connected in an array determines the total amount of generated electricity.

Electrical panels distribute the energy created by your Photovoltaic System to your building/home and local utility grid. Overproduction of power goes into your city's utilities, running your meter backwards. This will allow for you to gain credit on the next utility bill.
Photovoltaic System owners are able to utilize a monitoring system to ensure that they are getting the most out of their PV System. Monitoring systems will track your Solar Energy production and compare it to the expected production your installer provided.
Which is equivalent to taking 16.2 million vehicles off the road and planting nearly 2 billion trees!
This can allow for consumers save in the range of $30,000 in their lifetime!
Earth's surface absorbs 120,000 terawatts of solar radiation – that's 20,000 times more power than what is necessary to energize the entire world!
